Description

SMART HUMIDIFIER

TECHNICAL FIELD 10001] The present invention relates to the technical field of smart home technology, and particularly to a smart humidifier.

BACKGROUND |0002] With the improvement of quality of life, more and more consumers prefer to place a humidifier in a room to increase the air humidity in the room. Especially when an air conditioner is turned on, the humidifier is maintained operation. However, the existing humidifier also suffers from mainly the following problems.

[0003] 1. The humidifier is often started manually by a consumer, upon which the consumer does not know the humidity of the environment when it is started.

[0004] 2. The function of the humidifier is simple, with which generally only clean water can be used to generate water vapor; and it is inconvenient if some fragrance or disinfectant is intended to be added by the consumer.

[0005] 3. The water tank of the humidifier is difficult to clean, and bacteria trend to grow in the water tank, causing an impact on the health of the consumers.

[0006] 4. In the humidifier, the water tank is generally pressed on the seat merely by virtue of the own weight of the water tank. When the humidifier is accidentally kicked by a consumer, the humidifier may be easily kicked over, causing the water in the seat to be poured out on the floor.

[0007] 5. When the humidifier is not used for a long period of time, the water stored in the water reservoir becomes dirty and is contaminated with bacteria. If water vapor is generated with this part of water, the health of the consumers may be easily impacted.

SUMMARY |0008] Embodiments of the present disclosure may provide a smart humidifier by which the water vapor produced from a water vapor channel is ensured to be as clean as possible and thus beneficial to human health. |0009] To solve the above technical problems, the following technical solution is adopted in the present invention. 10010] According to one aspect of an embodiment of the disclosure, a smart humidifier comprises a seat, in which a water reservoir is disposed in the seat, a water vapor generator is 1 mounted in the water reservoir, and a water tank is mounted on the seat. A water vapor channel is provided in the water tank, and the water in the water reservoir comes out via the water vapor channel after the action of the water vapor generator. The seat further comprises a spent water chamber, and a spent water box is detachably connected in the spent water chamber. A water stop is provided between the spent water chamber and the water reservoir, and the water stop is movably installed in the seat. A guide nozzle is installed in the water reservoir. When the humidifier is started to operate, the nozzle starts to direct the water in the water reservoir to flow towards the spent water chamber and flush aside the water stop.

[0011] Preferably, the water reservoir comprises a first water storage section and a second water storage section. The first water storage section is of a semicircular shape, and the second water storage section is of a semi-elliptical shape. The nozzle directs the water in the first water storage section to flow to the second water storage section, and the spent water chamber is in communication with the second water storage section.

[0012] Preferably, a spent water flow-through hole is provided between the second water storage section and the spent water chamber, and the water stop is disposed at the position of the spent water flow-through hole.

[0013] Preferably, the water stop is rotatably connected to the seat, and a reset torsion spring is provided between the seat and the water stop.

[0014] Preferably, the spent water chamber extends to the circumferential side surface of the seat, and the spent water box is slidably installed in the spent water chamber.

[0015] Preferably, a lower viewing window for viewing the liquid level in the spent water box is provided on the outer surface of the spent water box.

[0016] Preferably, a plurality of the nozzles is arranged and distributed on the sidewall of the water reservoir, in which each of the nozzles sprays towards the spent water chamber.

[0017] One or more embodiments of the present disclosure may provide the following beneficial effects.

[0018] In the present invention, a spent water chamber is disposed in the seat, and a spent water box is detachably connected in the spent water chamber. Moreover, a nozzle is provided in the water reservoir. When the humidifier is started to operate, the nozzle starts to direct the water in the water reservoir to flow towards the spent water chamber and flush aside the water stop. After the humidifier is not used for a long time, the water stored in the water reservoir becomes dirty and is contaminated with bacteria. Through such a design, the residual water stored in the water reservoir will be drained firstly by the use of the nozzle and the spent water box, before the humidifier starts to generate water vapor. As a result, the relatively clean water in the water tank is allowed to enter the water reservoir, so as to ensure that the water vapor generated by the humidifier is as clean as possible. Moreover, the nozzle has a flow guide effect that also functions to clean the water reservoir, so that scale is unlikely to be deposited in the water reservoir, and the water reservoir is easy to be cleaned. |0019] In addition, for other structures, such as a shape structure with optimized water reservoir, the flow guide effect of the nozzle becomes better, and the residual water is more likely to be guided into the waste water box. Moreover, the water stop is automatically reset by the torsion spring, such that the cost is lower and the reset effect is better. |0020] These features and advantages of the present invention will be disclosed in detail in the following detailed description and accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS |0021] The present invention will be further described with reference to accompanying drawings, in which |0022] FIG. 1 is a view schematically showing the structure of a humidifier according to the first embodiment of the present invention; |0023] FIG. 2 is a view schematically showing the top structure of the humidifier according to the first embodiment of the present invention; ]0024] FIG. 3 is an exploded view of the humidifier according to the first embodiment of the present invention; [0025] FIG. 4 is a view schematically showing the structure of a seat according to the first embodiment of the present invention; and [0026] FIG. 5 is a top view schematically showing the seat according to the first embodiment of the present invention.

DESCRIPTION OF THE EMBODIMENTS

[0027] Hereinafter, the technical solutions of the embodiments of the present invention are explained and illustrated in conjunction with the accompanying drawings of the embodiments of the present invention. However, the following embodiments are merely preferred embodiments of the present invention, and not exhaustive. Other embodiments obtained based on the embodiments herein by those skilled in the art without any creative efforts fall within the protection scope of the present invention. |0028] In the following, the terms indicating the orientation or position relationships such as "inner", "outer", "upper", "lower", "left", and "right" are based on the orientation or position relationships as shown in the figures, and are used herein for convenience and ease of description, instead of indicating or implying that the device or element described should have a particular orientation or be constructed and operated in a specific orientation, and thus cannot be interpreted as a limitation of the present invention.

[0029] First Embodiment [0030] As shown in FIGs. 1 to 5, a humidifier is provided in this embodiment, which comprises a seat 1, in which a water reservoir 11 is disposed in the seat 1, a water vapor generator 12 that is preferably an ultrasonic vibrator is mounted in the water reservoir 11, and a water tank 2 is mounted on the seat 1. A water outlet is disposed at a bottom of the water tank 2, and the water in the water tank 2 flows through the water outlet into the water reservoir 11 in the seat 1. A water vapor channel is provided in the water tank 2, and the water in the water reservoir 11 comes out via the water vapor channel 21 after the action of the water vapor generator 12.

[0031] In this embodiment, the water tank 2 includes an inner water storage chamber, and an additive box 3 accommodating additives is provided on the water tank 2, where the additive box 3 communicates with the inner water storage chamber. The additive box 3 is provided with an ejector 31 for ejecting the additive in the additive box 3 into the inner water storage chamber, and also a box cover 32.

[0032] In this embodiment, when the additive box 3 is provided, the additive box 3 may accommodate a fragrance, or some acetic acid for disinfection. Such additives may be freely added by a consumer according to his/her own needs, such that the humidifier does not target clean water solely, and the consumer can have more choices. For example, when the additive is a fragrance, the water vapor generated by the humidifier can be used as an air freshener. For example, when the additive is acetic acid, the humidifier may be used as an indoor disinfector by the consumer. Of course, the additive may also be other products. At this time, the function of the humidifier will also change if other products are present, which is very convenient.

[0033] In order to optimize the design and extend the service time of the additive, the ejector 31 is connected to a control unit, and a timing module is provided in the control unit, where the timing module controls the ejector 31 to eject periodically. When the timing module is provided, the additive in the additive box 3 can be ejected periodically, such that the additive in the additive box will not be ejected out all at once. Moreover, the timed ejection has the advantage that the concentration after mixing in the water tank 2 is ensured to be more uniform, thus achieving a better sustained effect.

[0034] In this embodiment, the control unit is preferably arranged in the seat 1. Because the seat 1 has adequate space, and generally an electrified component is also arranged in the seat 1, so it is preferred that the control unit is arranged in the seat 1. A first electrical connector 41 is provided on the seat 1, and a second electrical connector 42 is provided on the water tank 2.

When the water tank 2 is mounted on the seat 1, the first electrical connector 41 and the second electrical connector 42 are electrically coupled. When the second electrical connector 42 is provided on the water tank 2, the water tank 2 is powered, thus energizing the ejector 31.

[0035] In this embodiment, the first electrical connector 41 is an electrical plug, and the second electrical connector 42 is an electrical slot. Such a connection mode has the advantages of simple structure, and good connection stability.

[0036] Through the conception of this embodiment, it is also readily conceivable by a person skilled in the art that the control unit may also be arranged on the water tank 2, on which a power supply element is further arranged, where the power supply element is connected to the control unit. The ejector 31 can also be energized through such an implementation.

[0037] To enhance the disinfection effect, an UV disinfection lamp 13 is provided in the water reservoir 11 in this embodiment. In this embodiment, a plurality of UV disinfection lamps 13 are provided and distributed on the inner sidewall of the water reservoir 11.

[0038] In addition, in order to allow the additive ejected into the water tank 2 to be well mixed with clean water, the tank 2 is provided with a stirring rod 5, where the stirring rod 5 is connected to a first motor, which is connected to the control unit in turn. By means of the stirring function of the stirring rod 5, when the additive is ejected into the water tank 2, the stirring rod 5 starts to rotate, such that that the additive can be well mixed with the clean water.

[0039] The stirring rod 5 has the following installation structure. The water vapor channel 21 has a circular cross section, and the stirring rod 5 includes an axial sleeve hole 51. That is, the stirring rod 5 includes a rod body and stirring blades provided on the rod body, where the rod body is a hollow rod that is sleeved on the water vapor channel 21. This structure design makes good use of the water vapor channel 21, where the stirring rod 5 is sleeved outside water vapor channel 21 through the axial sleeve hole 51, with no need of an additional rotation shaft, making the structure more compact. The first motor in this embodiment is preferably a waterproof motor.

[0040] Moreover, an automatic control method is adopted for the ejector 31 in the humidifier in this embodiment. After each ejection by the ejector 31, the stirring rod 5 starts stirring, where the control unit controls the starting time of the stirring rod 5 to be later than the starting time of the ejection of the ejector 31. The purpose of such a design is to allow the ejected additive to completely enter the clean water after the ejector 31 ejects the additive before stirring, so that the system can be more fully stirred. The starting time of the stirring rod 5 is 3-10 s, and preferably 5 s later than the starting time of the ejection of the ejector 31.

[0041] A conventional humidifier usually has a detachable connection between the water tank 2 and the seat 1, but the water tank 2 itself cannot be detached, resulting in a large amount of scale deposit that cannot be cleaned in the water tank 2 after being used for a long period of time. In order to solve the problem, in this embodiment, the water tank 2 includes a water tank body 201 and a water tank bottom cover 202. The water tank body 201 and the water tank bottom cover 202 are detachably connected. The water tank body 201 and the water tank bottom cover 202 are provided with a first seal ring therebetween.

[0042] In this embodiment, the water tank 2 is divided into a water tank body 201 and a water tank bottom cover 202, in which the water tank body 201 and the water tank bottom cover 202 are detachably connected. Through such a design, after the water tank 2 is used for a long period of time, the water tank body 201 and the water tank bottom cover 202 are detached from each other, and then cleaned separately. In this way, it is ensured that no dirt will accumulate in the water tank 2 and the newly injected water in the water tank 2 will not be polluted. In addition, the first seal ring is provided between the water tank body 201 and the water tank bottom cover 202, and the first seal ring can guarantee the tightness between the water tank body 201 and the water tank bottom cover 202, and thus ensures that no water is leaked out.

[0043] In this embodiment, the water tank body 201 and the water tank bottom cover 202 are detachably connected as follows.

[0044] The water tank bottom cover 202 is provided with at least two first notches 22, and preferably four first notches 22 in this embodiment. Specifically, as shown in FIG. 3, a first locking pin 23 is slidably disposed at the first notch 22, and the water tank bottom cover 202 is further provided with a chute communicating with the first notch 22, in which the first locking pin 23 is slidably mounted in the chute. At a bottom of the water tank body 201, a locking foot 24 corresponding to the first notch 22 is provided, and preferably four locking feet 24 are provided. The locking foot 24 is internally provided with a first locking slot 241 for accommodating the first locking pin 23. The first locking pin 23 includes a toggle portion 231 exposed on a circumferential side surface of the water tank bottom cover 202. When a consumer toggles the first locking pin 23, the first locking pin 23 is inserted into or disconnected from the first locking slot 241, so that the connection between the water tank body 201 and the water tank bottom cover 202 is secured.

[0045] Preferably, at a bottom of the locking foot 24, a guide surface 242 for facilitating inserting of the first locking pin 23 into the locking foot 24 is provided. The guide surface 242 is provided for the purpose of preventing the damage or destroy caused to the first locking pin 23 when the water tank body 201 is directly mounted on the water tank bottom cover 202 when the consumer forgets to slide the first locking pin 23 to a locked position. After the guide surface 242 is provided, even if the consumer forgets to slide the first locking pin 23 to the locked position, it is also possible to guide the first locking pin 23 to be inserted into the locking foot 24 by means of the guide surface 242.

[0046] In order to facilitate the consumer to view the presence or absence of scale deposit in the water tank 2, the water tank body 201 in this embodiment is provided with an upper viewing window 25 for viewing the internal cleanness of the water tank body 201. In addition, for further improving the cleaning effect in this embodiment, the stirring rod 5 can be removed and replaced with a cleaning brush sleeve. The cleaning brush sleeve can also be sleeved outside the water vapor channel 21 and driven by the first motor.

[0047] In addition, in a conventional humidifier, the water tank 2 is pressed on the seat 1 merely by virtue of the own weight of the water tank 2. When the humidifier is accidentally kicked by a consumer, the humidifier may be easily kicked over, causing the water in the seat 1 to be poured out on the floor. To solve the technical problem, at least one limiting hook 26 protrudes downwards from the bottom of the water tank 2, and a slot 14 into which the limiting hook 26 is extended is provided on the seat 1. A limiting pin 15 is movably installed in the slot 14, which cooperates with the limiting hook 26 to limit the water tank 2 from being separated from the seat 1. A seal is provided between the seat 1 and the water tank 2. The seal is preferably a second seal ring, and the seat 1 is provided with a seal groove for accommodating the second seal ring.

[0048] In this embodiment, through the cooperation between the limiting hook 26 and the limiting pin 15, the seat 1 is prevented from being separated from the water tank 2. Even if the humidifier is accidentally kicked by a consumer, the water tank 2 and the seat 1 are still maintained to be connected, so that the water in the seat 1 is not easy to be poured out. Meanwhile, a seal is further provided between the seat 1 and the water tank 2 in this embodiment. When the limiting pin 15 is inserted into the slot 14, the second sealing ring is in a compressed state so that even if the water tank 2 and the seat 1 are kicked over, there is almost no water spilled out between the water tank 2 and the seat 1, whereby the floor can be kept clean and tidy.

[0049] Similar to the connection between the water tank body 201 and the water tank bottom cover 202, in this embodiment, the seat 1 is provided with a sliding groove communicating with the slot 14, and the limiting pin 15 is slidably mounted in the sliding groove. The limiting pin 15 includes a pulling end 151 exposed on a circumferential side surface of the seat 1. Similarly, at a bottom of the limiting hook 26, a guide slope is provided. The guide slope has similar function to that of the guide surface 242 on the locking foot 24, and thus is not elaborated herein again.

[0050] Preferably two or more limiting hooks 26 are present. However, due to the plug-in-coupling of the first electrical connector 41 and the second electrical connector 42 between the water tank 2 and the seat 1 in this embodiment, maybe only one limiting hook 26 is employed in this embodiment. The limiting hook 26 is preferably located at an opposite side on the seat 1, and the connection line of the two runs through the centre of the seat 1, because this design has good stability.

[0051] In a conventional humidifier, a lower water injection port is generally provided at the bottom of the water tank 2. However, in this embodiment, due to the presence of a connection between the water tank 2 and the seat 1, if water needs to be added at ordinary times, the limiting pin 15 has to be toggled for detachment. This is inconvenient. Therefore, in order to facilitate the consumer to add water, in this embodiment, a top water injection port 27 is provided on the top of the water tank 2, so that the consumer has no need to detach the seat 1 from the water tank 2 when filling water, thereby facilitating the injection of water.

[0052] Meanwhile, in order to prevent the dust or the like from entering the top water injection port 27, the water tank 2 has an upper cover 271 mounted on the top water injection port 27. Moreover, a pulley is preferably disposed at the bottom of the seat 1 in this embodiment. The pulley is disposed for the purpose of reducing the possibility of lateroversion by means of the rolling of the humidifier when the humidifier is kicked by a consumer, and also for the purpose of facilitating the movement of the humidifier. The pulley in this embodiment is not shown in the figure.

[0053] In addition, when the conventional humidifier is not used for a long period of time, the water stored in the seat 1 will become dirty and be contaminated with bacteria. If water vapor is further generated with this part of water, the health of the consumers may be easily impacted. Therefore, in this embodiment, the seat 1 further includes a spent water chamber 16, and a spent water box 6 is detachably connected in the spent water chamber 16. A water stop is provided between the spent water chamber 16 and the water reservoir 11, and the water stop is movably installed in the seat 1. A nozzle 17 is installed in the water reservoir 11. When the humidifier is started to operate, the nozzle 17 starts to direct the water in the water reservoir 11 to flow towards the spent water chamber and flush aside the water stop.

[0054] After such humidifier is not used for a long time, the water stored in the water reservoir 11 becomes dirty and is contaminated with bacteria. Through such a design, the residual water stored in the water reservoir 11 will be drained firstly by the use of the nozzle 17 and the spent water box 6, before the humidifier starts to generate water vapor. As a result, the relatively clean water in the water tank 2 is allowed to enter the water reservoir 11, so as to ensure that the water vapor generated by the humidifier is as clean as possible. Moreover, the nozzle 17 has a flow guide effect similar to that of the flushing process, and thus a cleaning effect can also be provided to the water reservoir 11, so that scale is unlikely to be deposited in the water reservoir 11, and the water reservoir 11 is easy to be cleaned.

[0055] For the structure of the water stop, a spent water flow-through hole 113 is provided between the water reservoir 11 and the spent water chamber 16, and the water stop is disposed at the position of the spent water flow-through hole 113 and rotatably connected to the seat 1. A reset torsion spring is provided between the seat 1 and the water stop. By using the elastic resetting action of the torsion spring, when the water in the water reservoir 11 is in a calm state, the water stop functions to retain the water, and prevent the water in the water reservoir 11 from entering the spent water chamber 16. When the water in the water reservoir 11 is pushed by the nozzle 17, the water flow impacts against the water stop. When the impact force of the water flow is greater than the spring force of the reset torsion spring, the water stop is flushed aside, so that the water in the water reservoir 11 can smoothly enter into the spent water chamber 16. When the nozzle 17 is out of operation, the water stop is reset again.

[0056] In this embodiment, a plurality of nozzles 17 is arranged and distributed on the sidewall of the water reservoir 11, in which each of the nozzles 17 sprays towards the spent water chamber 16. The arrangement of the plurality of nozzles 17 enables a better guide effect, and ensures to the maximum extent that the residual water in multiple positions is flushed away.

[0057] In order to increase the flow guide effect for residual water, the shape and structure of the water reservoir 11 are optimized in this embodiment. The water reservoir 11 comprises a first water storage section 111 and a second water storage section 112. The first water storage section 111 is of a semicircular shape, and the second water storage section 112 is of a semi-elliptical shape. The nozzle 17 directs the water in the first water storage section 111 to flow to the second water storage section 112, and the spent water chamber 16 is in communication with the second water storage section 112. The first water storage section 111 is arranged to have a semicircular shape, and the second water storage section 112 is arranged to have a semi-elliptical shape. The semi-elliptical design allows the waste water to be concentrated at an end portion for discharge, and the flow guide direction tends to be uniform, so no problem of disordered flow guide direction occurs, and the drainage effect is better.

[0058] Meanwhile, in order to allow a consumer to more intuitively get to know the amount of the spent water in the spent water box 6, a lower viewing window 61 for viewing the liquid level in the spent water box 6 is provided on the outer surface of the spent water box 6 in this embodiment. Through the lower visible window 61, the consumer can see the level of the wastewater in the waste cartridge 6. The liquid level of the spent water in the spent water box 6 can be viewed by the consumer through the lower viewing window 61.

[0059] To make the starting of the nozzle 17 more smart, the smart humidifier further includes a control unit. A timing unit is disposed in the control unit, which is used to record the starting time and the stopping time of the smart humidifier. A default value T is set in the control unit, when the time interval between the last stopping time and the current starting time of the smart humidifier is greater than the default value T, the control unit controls the nozzle 17 to start.

[0060] With this control method, the starting of the nozzle 17 by the humidifier becomes smarter. When the time interval between the last stopping time and the current starting time is less than the default value, the nozzle 17 will not be started. Therefore, the nozzle 17 is not started to operate if the two operations of the humidifier are close in time, thus reducing the unnecessary starting times, lowering the energy consumption, and also saving water.

[0061] Preferably, the default value T is more than 6 hours, because the residual water in the water reservoir 11 is relatively clean and not contaminated with excessive bacteria within 6 hours. Therefore, even if water vapor is generated with this part of residual water, no adverse effects are caused. In addition, for the spray time of the nozzle 17, the control unit controls the nozzle 17 to continuously operate for 5 to 10 seconds, and preferably about 6 seconds. If the time is too short, the drainage effect is less good; and if the time is too long, the water newly entering the water reservoir 11 from the tank 2 is caused to be drained, thus resulting in the waste of water resources.

[0062] In addition, for a conventional humidifier, the starting is performed manually and less smart. In this embodiment, the seat 1 or the water tank 2 is provided with a humidity sensor for sensing the ambient humidity. The humidity sensor is connected to the control unit, which includes a memory module. The memory module includes at least one humidity memory value. When the humidity memory value is equal to the humidity data sensed by the humidity sensor, the control unit controls the water vapor generator 12 to start or stop.

[0063] In this embodiment, the humidifier is provided with a humidity sensor that can sense the humidity of the indoor environment. When the humidity is sensed to be too low, the humidifier can be automatically started, and when the humidity is sensed to be too high, the humidifier can be automatically stopped. This control mode is smarter, so as to avoid the starting of the humidifier when the indoor humidity is too high. This is much beneficial to human health.

[0064] In addition, in this embodiment, the control unit also includes a memory module, and at least one humidity memory value is stored in the memory module, which allows the consumer to customize a preset humidity value according to his/her own physical condition. For example, for patients having rheumatic diseases, the humidity memory value can be set to a relatively low value; and for a patient susceptible to cough, the humidity memory value can be set to a relatively high value. After setting, the humidifier will be started or stopped smartly based on the value set by the consumer, which is very beneficial to human health.

[0065] In this embodiment, the humidity sensor is preferably provided on the seat 1, and a display screen is further provided on the seat 1, where the humidity data sensed by the humidity sensor is displayed on the display screen 18, such that the humidity in the room can be conveniently and visually viewed by the consumer. In addition, the seat 1 is provided with at least one memory switch. The memory switch is used to select a corresponding humidity memory value. A plurality of memory switches is provided so as to be flexibly switched between different consumers. For example, a memory switch setting is suitable for rheumatic patients, and the other is suitable for those susceptible to dry mouth, whereby one-button switching is achieved with high convenience.

[0066] The control unit includes a timing module, and the timing module is connected to the humidity sensor to control the humidity sensor to start at regular intervals. The working principle of the timing module is the same as the timing module for the ejector 31, but they are two timing modules operating independently. The timing module for the ejector 31 is the first timing module, the timing module of the humidity sensor is the second timing module, and both timing modules are integrated in the control unit. The timing module set for the humidity sensor allows the humidity sensor to start sensing periodically, with no need of operation for a long time. In this way, the service life of the humidity sensor is prolonged and the energy consumption is reduced.

[0067] Moreover, in order to better control the humidifier smartly according to the indoor environment conditions, an air supply passage 19 is provided in the seat 1 in this embodiment, and a fan for blowing air to the water vapor channel 21 is disposed in the air supply passage 19. The fan is connected to a fan motor, and the fan motor is controlled by the control unit. That is, the control unit can control the fan motor to start or stop. More precisely, the rotational speed of the fan motor can be controlled so as to control the air supply rate and thus the amount of water vapor entering the environment per unit of time.

[0068] For example, when the indoor humidity is too large, a low air supply rate is selected. At this time, the rotational speed of the fan motor is decreased under the control of the control unit. If the indoor humidity is too small, a high air supply rate is selected. Whether the indoor humidity is too large or too small is determined by comparing the set value in the control unit with the data sensed by the humidity sensor.

[0069] Furthermore, there are also consumers that prefer a constant air supply rate. In order to increase the consumer's choice, the fan motor is connected to a rotational speed adjustment circuit including a first circuit and a second circuit. The first and second circuits are interlock circuits, where the first circuit controls the fan motor to operate at a constant rotational speed, and the second circuit controls the rotational speed of the fan motor to be inversely proportional to the humidity data sensed by the humidity sensor. The first and second circuits are interlock circuits, that is, only one of them can be selected to work.

[0070] For facilitating the selection by the consumer, the seat 1 is provided with a first switch for turning on the first circuit and a second switch for turning on the second circuit, where the first and second switches are interlock switches. When the first switch is closed, only the first circuit works, and when the second switch is closed, only the second circuit works [0071] In addition, in order to improve the accuracy of the smartness, when it is determined whether the humidity memory value and the humidity data sensed by the humidity sensor are equal, the humidity data sensed is obtained by averaging at least two pieces of humidity data collected by the humidity sensor at an interval. By averaging after the values are collected, the sensed humidity is more accurate, thereby reducing the chance of inappropriate starting. Moreover, the time interval between two adjacent acquisitions by the humidity sensor is 1 to 10 s.

[0072] The above description is merely the specific embodiments of the present invention, and the protection scope of the present invention is not limited thereto.
